Recycling back of outlet stream to the reactor from an ideal CSTR carrying out a first order liquid phase reaction will result in __________ in conversion. No change Decrease Either A or B, depends on the type of reaction Increase TRUE ANSWER : ? YOUR ANSWER : ?
Helium-mercury method can be used to determine the __________ of the catalyst particle. Pore volume Porosity All of these Solid density TRUE ANSWER : ? YOUR ANSWER : ?
The ratio of volume of mixed reactor to the volume of P.F.R. (for identical flow rate, feed composition and conversion) for zero order reaction is 1 > 1 ∞ TRUE ANSWER : ? YOUR ANSWER : ?
The reaction rate almost gets doubled for 10°C rise in temperature. This is due to the fact that the Collision frequency increases Fraction of molecules having threshold energy increases Increased temperature reduces the activation energy Value of threshold energy decreases TRUE ANSWER : ? YOUR ANSWER : ?
